An ad hoc wireless mobile network is an infrastructure-less mobile network that has no fixed routers; instead, all nodes are capable of movement and can be connected dynamically in an arbitrary manner. In order to facilitate communication of mobile nodes that may not be within the wireless range of each other, an efficient routing protocol is used to discover routes between nodes so that messag...

When a link fails in an IP network, the network re-converges to redirect the traffic away from the failed link. IP fast reroute is used to minimize the time taken to redirect the traffic to an alternate path. Multiple routing configurations (MRC) is the IP fast reroute scheme under consideration. In this paper, we will discuss how to minimize the impact of the MRC recovery process on the post f...

Hash-based load-balancing techniques are widely used to distribute the load over multiple forwarding paths and preserve the packet sequence of transport-level flows. Forcing a long-lived, i.e., elephant, flow to follow a specific path in the network is a desired mechanism in data center networks to avoid crossing hot spots. This limits the formation of bottlenecks and so improves the network us...

This paper studies the performance of multi-homed transport protocols tolerant of network failure. It evaluates the performance of different retransmission policies combined with path failure detection thresholds, infinite or finite receive buffers for various path bandwidths, delays and loss rate conditions through SCTP simulation. The results show that retransmission policies perform differen...

In this paper, a new SCTP congestion control mechanism is introduced in multi-homing mode. Congestion in each route can be avoided or can be controlled, based on an Active Queue Management (AQM) method. Also, routers compute probability of congestion for the sources on the paths and then notify them. Therefore, the sources can adjust their sending rates on each path effectively and if necessary...

Fast load balancing is of the highest importance to utilize the resources effectively and improve the performance of the Multi Protocol Label Switching (MPLS) enabled Internet Protocol (IP) networks. Load balancing splits a part of traffic called splitting ratio from the maximum loaded path in to minimum loaded path. One very strong constrain in balancing the load is the tradeoff between the de...

Many simulation models contain one or more transport systems where some type of vehicle, perhaps an AGV, a fork truck, a shuttle, or a human being, travel along predefined paths. Locations along the paths may specify where loads carried by the vehicle transfer to or from it, where some activity takes place requiring the vehicle’s presence, or where vehicle routing logic executes. This paper foc...

This paper proposes a simple path diversity algorithm (SPDA) for Inter domain routing. The SPDA uses source routing to find an alternate path from a source to a destination, and allows flexible division of traffic over the best and alternate path. The SPDA comprises three steps. First, the BGP protocol is extended to allow the BGP routing table to save the multiple paths for any destination. Se...
